TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 621,389, dated March21, 1899.

Application filed November 16,1897. Serial No. 658,730. (No model.)

type writing machines and comprises devices by means of which theoperator is enabled to write a whole page without moving his hands fromthe keyboardthat is to say, the return of the paper to the line-startingpoint and the spacing between the lines are simultaneously effected byacting upon a special key.-

The new action is produced according to these improvements in thefollowing manner:

' Bythe motion of the key-levers during writin g the paper is moved asusual, and a spring connected with it is strained until the end of theline is reached, when the depression of a special key releases thespring, which then restores the paper to the line-starting point, thespacing between the lines being simultane= ously effected.

The practical use of the new devices is illustrated by the accompanyingdrawings, which represent parts of a machine, and in which Figure 1represents a cross-section through the type-writing machine; Fig. 2, afront view of the principal parts; Fig. 3, the key and its accessoriesfor spacing between the lines and effecting the return of the paper;Figs. 4, 5, and 6, details.

As represented by the drawings, the papercylinder 0., which is shown inlongitudinal and cross sections, respectively, by Figs. 5 and 6,consists of a shell made of vulcanite or other suitable material, closedat the ends by the disks 1) b, which can rotate on the shaft 0, formedwith square ends mounted in the frame cl, surrounding the cylinder in ahorizontal direction. This frame is carried between rollers e amountedon the brackets e, fixed upon the middle frame f, which'when the machineis being worked rests upon the bottom frame g. The middle frame ispivoted at s to the lower frame g to enable the carriage to be turned upvertically to enable the operator to examine his work and for otherpurposes. A projection s prevents the carriage being overturned. Thearrangement of the keys and key-levers may be on any approved system.That which is indicated by the drawings is the Remington arrangement.The middle frame f is provided with an apertured lug f having a securingmeans f whereby the said frame is held in the position shown in Fig. 2.

After any of the keys has been depressed for the production of a letteror space and while the key is on its return stroke the cylinder a movesthrough a unitof its circumference around the shaft 0, this unit beingexactly equal to the distance between two contiguous letters in thewriting. At the end of the line the key'z is depressed, and this actionreturns the cylinder to its original starting position and at the sametime displaces the cylinder longitudinally to a distance equal to thedistance between the centers of two lines of writing. The devices forobtaining these results form the more important fea tures of thisinvention.

A cross-bar k is arranged below the keylevers i, so as to be moveddownward when any of the keys 2! is depressed. A light rod Z, connectedwith the bar 10-, thereupon moves the double-armed lever m upon itsfulcrum m, fixed upon the lower frame 9. The lower member of this leveris fitted with a frictionroller m which is in contact with the lower armof the lever 'n upon a bracket 0 on the frame f. The motion of the baris thus translated to a pawl n fitted upon the upper arm of the lever 'nand engaging with the teeth of a ratchet-wheelp, so that when a key isdepressed the pawl slides over one tooth, a click or detent preventingthe movement of the wheel in the same direction. On the return stroke ofthe key the wheel 19 is rotated through the space of one tooth by thespring a pulling on the lower member of the lever n. The ratchet-wheel pis mounted so as to rotate freely upon the sleeve q, (see section Fig.4,) so that its lateral displacement is prevented. This sleeve ismounted upon the square shaft T, which is journaled at its ends in theframe d, Fig. 2. The shaft r'is thus enabled to rotate with the sleeve qand to move freely in a longitudinal direction through it independentlyof the movement of the ratchetwheel 1). There is mounted upon the shaft0' a dog-tooth or other clutch a, capable of engaging with and of beingdisengaged from the ratchet-wheel 1), whereby the motion of theratchet-wheel can be transmitted to the square shaft '2' when the clutchis in engagement. The center teeth a are arranged on the face of theratchet-wheel 1) so that the center may be moved into engagementtherewith, as it will be understood. This shaft has fixed upon it apinion v, gearing with teeth 12 formed upon the part b of the cylinder.The motion of the bar 7.: is thus ultimately communicated to thepaper-cylinder a.

The return of the paper-cylinder to its precise starting position issecured at the commencement of each line of writing by means of arms ww, which are fixed at suitable intervals upon the shaft 0 within thecylinder, as shOWn by Figs. 5 and 6, in combination with thelongitudinal rib a. The ends of the arms where they touch the rib may befaced with felt or rubber. Then the type-writer or operator is working,the rotation of the cylinder moves the rib step by step away from thearms 1010. By this rotation of the cylinder a helical spring 3 inclosedwithin a casing, part of which is shown as being broken away in Fig. 1,becomes gradually wound up, thus accumulating power, which is utilizedfor producing the line-spacing movement, as hereinafter described, onthe motion of the key .2.

As shown by Fig. 3, the key-lever z is connected by a light rod with thebell-crank lever 50 m, which oscillates upon the shaft min a verticalplane at right angles with the axis of the cylinder a. The arm to ofthis lever has the form of a sector of a disk, one side of which isinclined relatively to the plane of its motion. In contact with theinclined part of to there is a friction-wheel 2 on the lower end of thelever, which engages at 3 3 with the before-mentioned clutch 16. Hencethe motion of the key 2 can actuate that clutch in such a manner thatwhen the key is depressed the clutch is disengaged, whereupon the spring1 being released, rotates the cylinder back to its starting position,the clutch and sleeve rotating also, but the ratchetwheel remainingstationary. It will be seen that it is the release of the ratchet-wheelwhich effects the release of the spring y, and that the cylinder rotatesbackward until stopped by the contact of its rib a with the arms 10 10at the starting position. Immediately upon the release of the key 2 therod Z, kept in a strained position by the spring 4, restores the clutchto engagement with the ratchet-wheel 1), so that the paper-cylinder isonce more obliged to participate in the rotary motion of the wheel.

The longitudinal motion of the cylinder at, which takes placesimultaneously with its backward rotation, may be effected in any knownmanner--as, for example, by means of the devices employed for the samepurpose in the Remington machine, as hereinafter described.

The carriage and shaft 1', during its motion at any time toward theleft, strains a spring with which the carriage is connected by the wireor cord 6. The carriage is heldin position by means of the double dogs7, carried on the frame (I and engaging with the teeth of a rack 8,which is carried by arms 10, fixed upon a shaft 9, mounted in the lowerframe 9. A lever 11, fixed upon the same shaft 9 between the arms 10, isattached by a light connecting-rod with the key-lever 2'. Thus when thekey 2 is actuated or the rack 8 is otherwise moved laterally thecarriage will be moved to the right through a distance equal to thepitch of the rack, which should correspond with the space between thecenters of the nearest lines of the writing.

If wider spaces between the lines are desired, it is necessary only todepress the key .2 two or more times. If it be desired to move thecarriage backward and forward to read the writing or to replace thepaper on the cylinder, the thumb-lever 5, Fig. 2, may be moved into avertical position. The end of this lever then comes into contact withand depresses an arm of the lever l, thereby disengaging the clutch u,whereupon the cylinder may be turned in any direction freely. Anindex-finger and scale 12 may be arranged in connection with the end I)of the cylinder to facilitate the return of the cylinder to the writingposition after it may have been moved for correction of the writing.Asignal-gong may be arranged upon the frame and a pros jection uponthecarriage to actuate it.

The paper may be secured upon the cylinder by means of the rings h h,which can be rotated the one within the other. The inner ring, as shown,however, is fixed and furnished with the grips 7L2 and pin 11, passingthrough an inclined slot 2" in the outer ring. The paper having beenarranged on the cylinder below the grips, the rings h are turned, whenthe pin and slot in each inner ring compel the outer rings to advancetoward the center of the cylinder and close the grips upon the paper.

Having thus described my invention, what I claim is 1. In a type-writingmachine, a cylinder, a longitudinal rib therein, arms on the shaft incontact with the rib, means for giving the cylinder a step-by-steprotation, means for returning the cylinder to the starting-point, a dogand rack for eifecting a longitudinal movement of the cylinder inspacing lines of writing, substantially as described.

2. In a type-writing machine, the combination and arrangement with thepaper-cylinder rotating on a fixed spindle of arms within the cylinderfixed upon its spindle, a longitudinal rib in contact with the arms atthe commencement of a line, means for giving the cylinder a step-by-steprotation a too wheel 19 mounted upon the sleeve, a clutchu mounted onthe square shaft and engaging with the sleeve, alever Z operating theclutch,

and an inclined sector as, operating the clutchlever, the key ,2,constructed and arranged substantially as and for the purposehereinbefore described and as illustrated by the accompanying drawings.

In testimony whereof I hereunto set my hand in presence of twowitnesses.
